Grade 23 ELI Titanium Wire

Grade 23 ELI titanium wire is produced for medical use under ASTM F136.

It is a low-interstitial Ti-6Al-4V alloy. Oxygen, nitrogen, and iron are tightly controlled.
The goal is not higher strength. The goal is stability.

In wire form, Grade 23 ELI is used where the material becomes part of a medical structure. Load-bearing parts. Fatigue-sensitive components.

Consistency matters more than peak numbers. Behavior must stay predictable over time.

The wire is supplied in cold drawn or annealed condition. Diameter control and surface cleanliness are treated as functional requirements.

This material is selected when standard Grade 5 is not enough for medical environments.

Why Grade 23 ELI Instead of Grade 5

Grade 23 ELI titanium wire is selected for medical consistency, not for higher strength.

Grade 5 already meets general strength requirements. The key difference is interstitial element control.

Grade 23 ELI is produced with lower limits on oxygen, nitrogen, and iron. This results in more stable mechanical behavior from batch to batch.

In medical applications, wire components are often exposed to long-term load and repeated cyclic stress. Under these conditions, predictable fatigue performance is more important than peak tensile strength.

Compared with standard Grade 5, Grade 23 ELI provides a narrower property range and improved reliability for medical structures.

For this reason, Grade 23 ELI is specified in ASTM F136 for implant-grade titanium products.

Bone Fixation Components

 

 

Grade 23 ELI titanium wire is used in orthopedic fixation components such as bone pins, small fixation screws, and cerclage wires for fracture stabilization.

As a Ti-6Al-4V ELI alloy, the material is produced with low interstitial content, supporting improved fracture toughness and fatigue resistance compared with standard medical titanium alloys.
This allows the wire to withstand cyclic loads generated by normal bone movement after implantation.

Surface condition is controlled to reduce tissue interaction during implantation.

Medical-grade material control under ASTM F136 supports consistent mechanical behavior in orthopedic fixation applications.

Dental Implants & Orthodontic Devices

 

 

Grade 23 ELI titanium wire is used in dental implants and orthodontic devices where biocompatibility and corrosion resistance are required.

In implant systems, the wire is applied in abutment connection elements and fixation components.

In orthodontic applications, Grade 23 ELI wire is processed into orthodontic arch wires.
Its elastic behavior supports controlled force delivery, while resistance to saliva corrosion allows long-term use without surface degradation.

Low interstitial content and medical-grade material control support consistent performance in dental applications.

Cardiovascular & Minimally Invasive Surgical Instruments

 

 

Grade 23 ELI titanium wire is used in cardiovascular and minimally invasive surgical instruments that require stable mechanical performance and biocompatibility.

Fine wire sizes are applied in braided stents, fixation wires, ligation clips, and surgical staples.
The material maintains shape under cyclic load and resists corrosion in body fluid environments.

Non-magnetic behavior supports use in implantable and electronic medical device structures.

 

Application Summary

Across orthopedic fixation, dental devices, and cardiovascular or minimally invasive instruments, Grade 23 ELI titanium wire is selected for one common reason: stable performance in medical load-bearing structures.

Low interstitial control supports predictable mechanical behavior under cyclic stress.
Biocompatibility and corrosion resistance allow long-term use in body fluid environments.

These characteristics make Grade 23 ELI suitable for medical components where reliability matters more than peak strength.

Grade 23 ELI titanium wire is inspected according to medical-grade requirements.

• Chemical composition is verified per heat.

Interstitial elements are controlled to meet ASTM F136 limits.
This ensures alloy identity and consistency.

• Diameter is measured along the wire length.

Dimensional stability affects load distribution and assembly fit in medical components.

• Mechanical properties are verified by batch.

Tensile strength, yield strength, and elongation are checked to confirm stable behavior under cyclic load.

• Surface condition is inspected visually.

Surface defects may reduce fatigue performance in implant-related applications.

• Mill Test Certificates are provided with full traceability.

Additional third-party inspection can be arranged when specified.

Packaging

Grade 23 medical titanium wire is packaged to protect surface integrity, dimensional accuracy, and cleanliness during storage and transport.

• Individually coiled or straight-packed based on wire diameter and customer requirements.
• Inner protection using medical-grade plastic film or PE sleeves to prevent surface contact.
• Vacuum sealing available for ultra-fine wires or long-term storage needs.
• Outer packaging with rigid cartons or wooden crates to avoid deformation during transit.
• Clear labeling for grade, diameter, lot number, and traceability reference.

Packaging methods are selected to minimize mechanical stress and contamination risk before final medical device processing.

Delivery

• Standard lead time: 7–15 working days for common diameters.
• Custom sizes or special surface conditions: delivery confirmed after order review.
• Global shipping by air or sea, with export-compliant packing.
• Full documentation support including packing list, commercial invoice, and material certification.

 

 

Grade 23 ELI titanium wire is supplied as a medical-grade raw material for further processing.
Its performance in service is influenced by multiple factors beyond the material itself.

• Material behavior

Low interstitial content supports stable mechanical behavior under cyclic loading.
This is particularly relevant for fine wire diameters used in implant-related structures.

• Forming and processing

Annealed wire is typically selected when bending, shaping, or forming is required.
Cold drawn wire is used where dimensional stability and tension retention are critical.

• Application boundaries

The wire is not a finished medical device.
Final performance depends on device design, surface treatment, and assembly method.

• Specification control

Diameter tolerance, supply condition, and delivery form should be confirmed before production.
Material selection should follow the requirements of the finished medical component.
